Ok. Added a preliminary draft of section 9.1, which talks about
switching out the parameters used in the original implementation with
syntax parameters. Also includes a brief tutorial on syntax
parameters, because they're

Hello list.
I have a small set of contracts that I am thinking of turning into a
planet package so I can use them across projects. My problem is, how do
I use the rackunit framework to test them? Here is the first few
contracts that I want to test:

R5RS or R6RS if possible.
For R5RS, you will want to add SRFI-6 to do this (you should always add
SRFI-23 and SRFI-6 to R5RS), and
In general, `with-output-to-string' and other applications of string
output ports work well here.

Is there some built in like write-to-string in some dialects, or some

You're correct, there is no success function in Rackunit. This will do:
(lambda () 'ok)
I.e. you don't need to signal success for a test to pass. People have
experimented with test frameworks where you have to signal success,
but it the general conclusion is that it's too much effort for the

In rackunit, a cps interface like:

Could be tested like:

But, the second check would be nicer as (success "not fo
